Video Transcript for Thule Accessories and Parts TH05820 Review

Today we're going to be taking a quick look at part number TH05820. This is the replacement easy step mounting kit for Thule cargo boxes. This is going to help replace your lost or damaged mounting hardware for the Thule evolution, part number TH672 and the Thule cascade XT, 676XT, 677XT, and 678XT, and again these are all roof mounted cargo boxes. This kit's going to include one complete set of mounting hardware for one cargo box. You're going to get your U bolts with the rubber protectors on there to protect the bottom of the crossbars. You're going to get your stickers.

These are going to be 15 stickers to cover up any exposed holes in the bottom floor of the box. It's going to limit the amount of moisture, dirt, and debris that gets up in the box from outside. You're going to get your plastic strips that sit underneath the easy snap housings. You're going to get all four easy snap housings, and two cargo straps to secure any cargo inside your box. Now on each side of the housing you're going to have tie down locations to run your strap through and over your gear. Really simple operation though.

Pretty simple, the U bolt's going to come up around from underneath the vehicle's crossbar. It's going to come up through the bottom of the box. These housings are going to be located inside the box at each mounting location. You'll need to rotate it open, just like that. When it's open it's going to be able to receive the U bolt.

You push that up there and it engages in this portion right here. What you do is you'd rotate the housing over, push down the red lever. That's going to lock the U bolt in place, making sure it creates a nice tight fit between the cargo box and the vehicle's roof rack system. You need to do that at all four locations. Once you're ready to loosen up the hardware, remove the box, you lift up on the red lever, open back up the housing.

It's going to allow the U bolt to disengage from the foot pack. Really simple operation. Again, this is going to include one fully kit for a full replacement of one cargo box when it comes to the mount assemblies. That's going to do it for today's review of part number TH05820. .

I ordered this from etrailer for my Volvo Weekender Cargo box. The Volvo Weekender is suppose to be a rebadge Thule 650 Adventurer box but I could not get a good answer from Thule or Volvo about that. Since I bought the box used, the seller did not have the OEM clamps that came with it. Volvo part number 8698491 is the standard replacement for this item. However, the part is very expensive and only sold in a kit of x1. Having to buy 4 clamps would have been outrageous, might as well have ordered a entire NEW Thule Box. Anyway, I called the good folks at etrailer and was able to ask about this kit. Since my Volvo box is a bit older, it only allows for the U Bolt clamp style. I just needed to make sure the size worked and the U bolt clamp fit over my stock 2011 Ford Explorer cross bars. The rep from etrailer promptly gave me measurements over the phone. I went to my garage and measured the holes and bingo, the 3.5 inch spacing is exactly the same. I ordered this kit at a great price and a box arrived 2 days later. I have since mounted my Volvo Weekender cargo box to my Explorer and am ready for a road trip to test this all out. Would I order with etrailer again??? YES! Without the help from phone support I would probably have been left to the very expensive other options.

I needed to replace two of the quick mounting units for my Thule luggage unit and originally spoke with Thule directly, then was directed to etrailer for a lower price for the pieces. Etrailer's price was $40.00 less than Thule's for the same mounting hardware. Second review is, I have a small trailer that I wanted to add additional stop/turn lights. The trailer is not your regular trailer, mfg by SPACE trailers, so I purchased the two long led lights and will add them to increase the trailer's visibility when on the road. Customer service was great; packaging was satisfactory (I've read a few reviews that note this discrepancy *erailer-take notice.* Other than that, the purchase was fine with no problems.

Full disclosure: I recently received my order for the EasySnap Mounting kit and have not even installed it yet. I believe this will be a great retrofit for my Thule Cascade box and will motivate me to use my box even for a single day at the lifts as opposed to carrying skis, boots, poles, etc inside my truck. This is more a review of my shopping experience with etrailer.com. Not only was etrailer.com the only retailer I found that carried this item the shopping experience was flawless and the communications post sale with status updates were really outstanding. etrailer.com really distinguished themselves with excellent customer service and I would recommend them to a freind.

I bought a used Thule Evolution cargo box with one slightly broken internal attachment clip. When I looked online for the part I found the perfect solution at etrailer with a replacement which is just one piece of a great set.
The new clips are super easy to install and easier to use than the original parts.
I put two clips into my box and I am keeping the rest as spares.
etrailer is amazing, I had my parts within two days, shipping was reasonable and everything came in a nice, secure box.
I can't say enough positives about my experience and I am a thoroughly satisfied customer.
Thank you to all the folks at etrailer for your help.

Needed one Mounting Unit and U hooks for a 10 year old Thule Evolution Roof Cargo Carrier,which are no longer available individually anywhere. ETRAILER had a complete set of four mechanisms with the U hooks (Replacement EasySnap Mounting Kit for Thule Cargo Boxes THO5820). Perfect fit and the carrier is attached to the crossbars securely. Disadvantage is that you have to order all four. Advantage will have replacement over the years to come as the box gets older and the parts may not be available. Phone Service in helping me find the correct unit was excellent and the shipping time was within a few days. Con: Had to pay for shipping.

I am very, very pleased by the service I received from etrailer. eTrailer will be my source for Thule parts in the future. As important as the easy selection and fast shipping was it was the content that separated etrailer from other providers. The information was rich, well presented and clear. As I closed the transaction I felt 100% confident that I had ordered the right part for my Thule Cascade cargo box. Several sites had the part I was looking for but etrailer's content and and well-organized web site wwas the differentiator. I got exactly what I needed and received it very quickly. I'll be back to etrailer in the future.

I watched the video prior to placing the order to be sure I could do this myself. The parts arrived. There are no paper instructions and of course forgot where I saw the video. I went back on the etrailer website and couldn't find the video. I called the 800 number and Patrick quickly looked up my order and helped me locate the video again.
I placed the cargo box on a pair of saw horses and in no time it was on the roof of my Crosstrek. Two days later it was loaded and I drove from Oregon to California.

Parts were the exact right fit to replace the existing Thule hardware. The only issue was a lack of description anywhere on the right configuration parts to replace the original hardware. This hardware works for both boxes with slide adjustments for the easy snap and predrilled hole boxes. Mine being the slide adjustment type, I removed the rubber pads from the kit and all works great. Lack of installation instructions means not just etrailer, but Thule and the entire web.

Big upgrade compare to manual screw-in connector type.
Good: easy to install, easy to lock the u-screw with a simple twist motion. Very secure, I have put about 3000 miles of travel with the roof box using these clam connectors and they held on firmly even in strong wind.
I took off 1 star because the screw hole sleve broke off the tip due to thin plastic. Other than that it is fantastic, make put up and take down roof box a breeze.

I ordered original Thule parts for my 15 year old Evolution cargo box and that's what etrailer shipped. The price was good and the order was processed quickly. This was my first order with etrailer and I would not hesitate to order again from them. If I had more money my order certainly would have been bigger. Looking forward to doing business with them again.

Great service. Shortly after placing my order I received an email stating my shipping method had been upgraded for free. That was nice! The only feedback I would have is that the product did not come with any instructions, but it was pretty easy to figure out. Product does what it says. Bottom line etrailer was great to do business with.

Showed up timely. Everything worked perfectly. Putting this together was pretty self-explanatory, though I did find it strange that there were no instructions included. Only thing I really had a question about though were the stickers that helped patch holes, but that info was provided in the video on etrailer.com. So no problem!

I lost one of the original mounts for our THULE "coffin". Hesitant to have to purchase a complete set, but once I did a google search and landed on e-trailer, the pricing was
very reasonable and the new style mounts are much nicer than the OEM. Fast ship, excellent communication with the automated shipping system, etc.

I recently purchased an old Thule Evolution 672 Cargo Box from a friend and the Easy Snap mounts were worn and two of them were broken. This kit fits the box perfectly. ETrailer.com were very helpful along the way and answered all of my questions within the same day. I will definitely do business with them again.

Shipping was fast and the product looks good but despite what others had said it does not match the hole centers or hole size of my thule Evolution 1600 cargo box so I had to send it back.

The width is 3-1/4 inches inside span. SportRack uses a 4 inch wide u-bolt on some of their products, see part # SR05493Replacement Mounting Hardware for SportRack Aero Cargo Carriers$24.60. If you have a Thule Sidekick box, check part # TH02943Replacement U-Bolt for Thule Sidekick Cargo Box$1.51.

I had borrowed a friend's Thule Evolution and the 'foot' of one of the locking pieces broke off, allowing the roof box to flail around on the roof my entire trip. I needed to replace the piece. etrailer had the kit available for much cheaper than Thule did, and it was incredibly easy to install.

This was the best money I ever spent! I upgraded the system on my older Thule rooftop box, and it has made getting ready for trips SO much easier than the cumbersome bolt -on system. etrailer provides great service , and all parts fit perfectly with my Thule box as advertised. Thanks etrailer!

Like earlier reviews, I was surprised that there were no instructions in the box. Since I was prepared to have no instructions, however, I methodically looked at my Cascade Thule and then the parts. I successfully mounted my Thule and am happy that I didn't have to buy a new Thule.

At first I was worried that there were no instructions, as i usually RTFM. However I found that the install took 15 easy minutes if you include opening the boxes. Not sure what to do with the dots and straps, but thanks.

The new latches are easier to operate. Two of the old locking devices were broken. The new locking devices operate easily and seem better constructed. Having everything new again is worth it. I recommend these.

There is a way to get replacement mounting hardware for a Thule Evolution 1600 or 1800, but the Replacement Quick Grip Mount Assembly, part # TH05738, is designed to be used on the Thule Atlantis 1600 XT - Premium Roof Rack Cargo Box - Silver - QuickGrip Mounts - 16 Cubic Feet.
The replacement hardware you would need is the Replacement EasySnap Mounting Kit for Thule Cargo Boxes, part # TH05820. This kit will be a conversion kit that will take the mounting hardware that is on your evolution...view full answer...

I know it's really tempting to want to upgrade a U-Bolt style attachment system on a cargo box to the more modern and infinitely more convenient to use quick grip type assembly like # TH05738 or # TH05820.
Thule doesn't recommend cutting slots or drilling holes in any box under any circumstances. Doing so, even if an effort is made to reinforce it, will weaken the connection to the vehicle crossbar in an unknown manner. This can cause the box to become an unintended projectile in the...view full answer...

I have actually come across this before and found that the hardware that is used by the Thule Summit cargo boxes was actually an earlier version of the QM3 Hardware, # TH04997. I spoke with my contact at Thule and she stated that you can retro-fit the EasySnap Mounting Kit, # TH05820, to the Summit cargo box but it will be a tight fit. As long as the crossbars on your vehicle are less than 3-1/4 inches thick and under 2 inches tall then the EasySnap kit will fit the crossbars.view full answer...

The Thule Cascade Cargo Box used Quick Snap hardware that is no longer available. But what you can do is to use the EasySnap hardware. For a complete kit there are a couple of options. You can use # 05704 or # TH05820.
If you need the plastic strips that go in the bottom of the box use part # TH05820. If you do not need the plastic strips then you can use the # 05704 kit.
For a single housing use # 14688 and the correct u-bolt is # 43216.view full answer...

The Thule 250 Combi Box cargo box is a very old box. About 31 years old to be exact. Thule has a lot of information available on discontinued boxes but even the 250 goes further back than what they cover. The mounting hardware is no longer available and they do not have a manual available for download.
However, installation hardware # SR04952 might work. You will want to take some measurements of your roof rack crossbars and compare these measurements to the picture I have included showing...view full answer...

The new mounting hardware you can use for the Thule Cascade cargo box is the Thule Replacement EasySnap Mounting Kit, part # TH05820. This kit uses the newer design EasySnap housings to attach the cargo box to factory crossbars that would run from side to side on your vehicle.
If your 2012 Toyota Sienna just has the factory side rails on the roof you will need to add the Thule Complete Crossroad Roof Rack Kit, part # TH45058, to be able to mount the cargo box to your vehicle.

There will be 4 U-bolts with EasySnap Kit, # TH05820, and according to my contact at Thule, this is the correct EasySnap hardware set to use for an Evolution 1600 or 1800 Cargo Carrier.

The Quick Grip mounts, # TH05738, are not designed to fit the Evolution cargo box without modification to the box. Making modifications can compromise the structural integrity of the box. If you are willing to make modifications, you can use the Quick Grips and you would need 1 cradle for each mount, # TH8523387001.

The replacement mounting hardware that you will need for your Thule Cascade cargo box is the EasySnap Mounting Kit, # TH05820. The u-bolts that are included with this kit will fit crossbars up to 3-1/4 inches wide. If you have factory crossbars, you will want to measure the width of the crossbars to see if your cargo box will mount directly to your factory crossbars.
If your factory crossbars are wider than 3-1/4 inches or you do not have factor crossbars, then you will need to add...view full answer...

I spoke with my contact at Thule and she stated that the the only hardware that has been tested on the Frontier Cargo Box is the EasySnap hardware, like # 14688.

You probably already know that the correct hardware for the Thule Adventurer cargo box is the QM3 hardware, # TH04997. Provided that the crossbar diameter is no larger than 3-5/8 inches, this hardware will fit the crossbars on the 2011 Subaru Outback.
If you wanted to replace the hardware with the EasySnap Mounting Kit, # TH05820, you would have to make modifications to the box. If you are prepared to make the necessary modifications, this kit will fit on crossbars that are no wider...view full answer...

After you have lined up the cargo box on your roof rack, you would take the Easy-Snap brackets and begin by attaching the rubber mounting pads to the brackets.
Then, you would lift up on the small, red safety tab on the bracket, and turn the blue handle piece counter clockwise until you hear it click. Once you have done this, take the bracket and line it up with the mounting holes that line up with your roof rack cross bar, with the red tab facing the rear side of the vehicle.

Hi there! I would be glad to help, but without any information on your cargo box it makes it difficult at best.

The mounting hardware for the Evolution cargo boxes is designed to fit around crossbars up to 3-1/4 inches wide. This will limit you to Thule square bars, AeroBlade bars, or Yakima round bars.
